- Abstract
It is shown that the alkalinity of pore fluid of high addition flyash concrete decreases more greatly than that of normal concrete after 7 days,closing to the threshold value of 11.5.Having added 10%lime and 1.5%Na2SO4 in flyash concrete,the alkalinity increased evidently without reducing its strength.
